GETTING THE RIGHT TREATMENT FOR YOU
Once you have been diagnosed with a B12 deficiency, treatment should consist of (in the UK) an initial series of injections (the loading dose) followed by regular (maintenance) injections for life.
If you have no neurological symptoms your loading dose should consist of 6 injections over 2 weeks followed by a maintenance injection every 8 to 12 weeks.
If you are displaying neurological symptoms loading dose should be injections on alternate days until there is no further improvement in symptoms followed by a maintenance injection every 8 weeks.
Maintenance injections are for life and should not be stopped regardless of the result of any future blood test.
